1. Measure the height – for some scale drawings.
   Not all scale drawings allow for height measurement. Check with your instructor if you have a question.
   1. If the animal has all four legs on the ground you have two options for measuring height:
      1. Measure height from the ground to the top of the head.
      2. Measure height from the ground to the top of its hind hip.
   2. If the animal has only two legs on the ground, measure height from the ground to the top of its head.
   3. Use the string again to measure the animal’s height in inches or centimeters.
   4. Record measurements on the Table of Cretaceous Critter Calculations. Be sure to record the unit of measurement.

Step 2: Calculate the life-size dimensions of Cretaceous Critters

I. Calculate life-size dimensions by multiplying string measurements by the scale used for drawings.

1. A. Cretaceous Critters were drawn the 1/50th scale so you would multiply measurements by 50.
• Example: Gryposaurus length = 13.3 cm x 50 = 665 cm
2. Record life-size measurements on the Table of Cretaceous Critter Calculations. Be sure to include the unit of measurement.
